Green Party Leader Eamon Ryan believes today is "shaping up to be a truly historic day for environmentalism in Ireland. The tide has turned on fossil fuels, and there is widespread political support now for a just transition to renewable power."

"If we are to keep global temperature rises below 1.5-2 degrees, avoiding climate chaos, then 80% of known fossil fuel reserves need to be left in the ground. By signing the Paris Agreement, Ireland committed to such a plan", he said.
